This style of CD storage cabinets stores CDs individually in pop-out inserts allowing easy access to the CD of your choice. Units range from small capacity (20) to large (400). The smaller units can sit on a table, desk, or shelf. The larger units are floor-standing with feet. All of the units could also be mounted on a wall (hardware not included). Like all of our products, these CD storage cabinets are made in the USA from real wood (red oak) and come fully assembled (except for attaching the feet, when required).FeaturesDual locking inserts securely hold the CDs in place. The removal of CDs is enhanced by a spring mechanism activated by slightly lifting the CD. This 'pops' the CD out slightly, allowing for easy removal.All of our products come fully assembled, with the exception of the units that need feet attached to the bottom of the unit. You can simply open the box and set the unit in place! Many of our units can be wall-mounted if you so choose. We recommend that you consider attaching the taller free-standing units to the wall if you are concerned about tipping, especially in the presence of rowdy pets and curious children. The feet are pre-drilled and are provided with appropriate hardware.
